"humanism, 1934; Serial in. warm A lllClai ms." (c1;10 f114) v This invention appertainsto the art of mask ing or 'stenciling apparatus, such apparatus be a ing used for the purpose of applying paint, lac.-. quer or other finishes to articles of manufacture.

" The present inventionembodies' anapparatus of the above type designed especially forthe ap.-' plication of marbleizedifinishes, so to'speak, to metal burial a ,vaultsy. but .the a principle; of constructiont'of the apparatus of the. invention is upon which the article to befinishedamayi be carried in the painting or finish applying operation. t y w. y Associated with 3 the supporting means are the masking devices proper, theisame comprising largely a stationaryacombi'nedback andtop section, a movable combined top" andfront section and movable end sections. Associated with the combined top' andfront section are certain counterbalancing weight :devices'which facilitate the easy 'andreadyslifting or said combined front and top section when it is desired'to place 'the article to be'flnish'edi'n the masking-, apparatus and remove it. Theend sections are automatically [movable to spreadpositions mower to aifordiready accessto' the article'to'be finished for purposes of itsremoval i and I for 'emplacing the same in theapparatus. 5 Additionally, I employ automatic operating parts by which when the articleiibeing finished has be'en placed iii-proper position in reference to the combined backand top section; upon lowei ing thecombinedfront and top-section the said automatic devices carried 'by the latter section will engage the end' sections and cause the same to assume their operative "closed positions, and- 40 when the combined top'andfront' sectionis elevated "to assume an {open positionj'automatic spring mechanism willact upon the end sections and caus the same to spread or open to render iteasytoremove the'finished"article. A full understanding -of my invention will be had upon" reference to the accompanying drawings, in wl1ich: '""Figure 1 is a'perspective view of the complete a paratus with the partsin closed operative'p'ositions' ready for the application of a" finish toan article enclosed by-the various sections-of the masking devicef. 1 a 1.. i 7 "Figure 2 is a front-view omitting the lifting cables, and framemeans, for the counterbalance weights and illustratingthecombined front-and top section elevated and the end sections spread apart as when the apparatus is ready to receive the burial vault or similar article tolbe treated for the purpose of applying the finish thereto. I -Figure 3;isaview somewhat similar to Figure 2 but showing a burial vault disposed in position ready for the closing togetherof the several sections of the masking apparatus,

Figure 4; is an end perspecti e view showing the masking enclosure as when enclosing the burial vault to be finished, the liftingchains nd cables broken away. j v l t 'Figure 5 is an end perspectivevlw of frag mentary nature looking somewhat from the front of the. apparatus and illustrating the parts seen iniFigure l a little more clearly. r Q Referring now to the drawings and specifical y. describing the invention, it will be notedfthat my apparatus includes two uprights .lfan'd 2' at the'u'p'perend of which are horizontalarms or beams 3; Suitable pulleys or sheaves are carried 7 by said beams or arr'ns3 and cables 4 passl about said pulleys each cable carrying at one enda weight 5 and beingattached atitslopp'osi te end to one end of the combined front and top,section of themasking Ienclosure, as shownujat t; The masking enclosure consists bf a' housing made up of a plurality of sections, whichjfoi' the purposes of this description will be designated the co'mbinedback and top section], the cornbined front and top section' 8 and ,thef'endsc tions '9. In generalQthe housing of the masking enclosure will conform to the shape rinter; tllewhill to be finished, and'in'gthe present instance, thelsaid sections 1, 8 and Qfare formed with slot-like openings [0 of" many different formations through which openings p aint,',la e -v. qu'er, or other finishing material may be sprayed when the sections 1, 8 and!) are in their closed positions, as illustrated in Figures 1, 3, 4. and'fi In order that the wall structure of the parts I; 8 and 9 may. be strong notwithstanding the formation of slotted openings HE therein as seen; it is contemplated to connect portionsTof these parts on opposite sides of the slottedopenings by means of stirrup or U-shapedmembers H which project outwardly from the outer surfaces oi the members and enablethepaint, lacquer, or other finishing material to i be sprayed through 'the openings l0, thepentire length of these openings, 5, The combined back i and mop ,section is sup: ported in a stationary manner by meansof yertical standards I2, and inorder to supportfthe burialjvault or 'other article to be finished in proper position in the masking enclosure suit posed in spaced relation to the base of said enclosure. 7

The end sections 9 of the masking enclosure are hinged at their rear edges, as shown at M,

land 5.

In otherwords, the tendencies of the springs l6 by their normal set is to pull the sections 9 outwardly after the manner shown in Figure 2 and the said springs constitute automatic means for doing the above work.

The combined front and top section 8 of 'th apparatus is equipped with laterally and downwardly inclined cam members I! which constitute automatic devices for engagement with the end sections 9 and these members come into play upon the downward closing movement of the section 8 for the purpose of engaging the parts 9 to force the same to closed positions, as illustrated in Figure 5.

7 With the construction of the invention set forth as above noted, the operation of my apparatus is very simple. In the emplacing of a burial vault or other article of manufacture in the masking enclosure, the parts will be arranged as shown in Figure 2. The article to be finished is then placed upon the base supporting rails l3, as shown in Figure 3. The operator then grasps the handle I8 which projectsfrom the outer side of the section 8 and pushes down upon this section so as to carry it to the position of Figure 1. This operation is performed with ease because of the use of the counterbalancing weights 5 which substantially counterbalance the weight of the section 8.

As the section 8 approaches its downward limit of movement, the automatic acting cam members I! engage with the upper edge portions of the end sections 9 and cause the end sections to close in toward the ends of the burial vault l9 as the section 8 reaches its operative closed position illustrated well in Figures 1, 4 and 5.

'It is to be understood that my masking enclosure may be of different shapes, and while for the purpose of giving a marbleized finish by the stenciling actions of the parts I, 8 and 9, I use a certain form and arrangement of the slotted openings I8, I wish it to beunderstood that I'do not want to be limited in r'eference to the specific form of the masking enclosure parts, or the spe- I cific arrangement of the said openings l0 because these phases of my invention may be modified-in a manner obvious to those versed in the art.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States, is: I 1.
